Deuteronomio  6, 13-8

Thou shalt fear the LORD thy God, and serve him, and shalt swear by his name. Then saith Jesus unto him, Get thee hence, Satan: for it is written, Thou shalt worship the Lord thy God, and him only shalt thou serve. And Cain talked with Abel his brother: and it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him.
